Study Notes
Oxygenation and Respiratory System
- Primary function of diffusion in the context of oxygenation: to facilitate the exchange of oxygen and carbon dioxide between the air we breathe and the blood.
Pulmonary Circulation
- Main function of pulmonary circulation in the respiratory system: to transport deoxygenated blood from the heart to the lungs, and then return oxygen-rich blood from the lungs to the heart.
Hypoxemia
- Definition of hypoxemia: a state of insufficient oxygen in the blood, characterized by low oxygen levels in the arterial blood.
Ventilation Regulation
- Regulation of ventilation in the lungs: controlled by the respiratory center in the brain, which responds to changes in blood carbon dioxide levels and pH.
Alveolar Gas Exchange
- Role of alveolar gas exchange in the respiratory process: to facilitate the exchange of oxygen and carbon dioxide between the air we breathe and the blood, allowing oxygen to enter the bloodstream and carbon dioxide to be removed.
Test your knowledge on the processes of breathing, gas exchange, anatomy and physiology of oxygenation, nursing interventions, and key terminologies related to oxygenation and respiratory system.
